This one can be obtained by chopping off the 48 vertices of an ex, which correspond to 2 vertex-inscribed
f-ico. In fact 48 ikepy are to be cut off.
But in contrast to sadi those ikepy would intersect here, resulting in teddi cells instead. –
Bidex likewise can be obtained from sadi by chopping off the 24 vertices of a further vertex-inscribed
f-ico.

The bidex vertex figure is a faceting of ike, having 4 (x,f,f)-triangles and 2 (x,x,x,f)-trapezia.
Btw., that vertex figure is a self-dual chiral polyhedron, in fact the dual is nothing but a rotated copy, i.e. dualization even
respects its handedness!

Bidex has swirlprismatic symmetry. In fact, it divides into 8 rings of 6 teddies each.
Therefore the edges of each teddi itself divide correspondingly into 2 classes in a chiral way!
